SPECIFICATION forming part of Letters Patent No. 419,550, dated January 14, 1890.

I Application filed May 18, 1889. Serial No. 311,249. (No model.)

To aZZ whom it may concern.-

Be it known that 1, WILLIAM LPARMALEE,

a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Skates, of which the following is a specification.

The object of myinvention is to construct an ice or roller skate'that can be adjusted to difierent-sized shoes, and after adjustment can be clamped longitudinally, substantially as hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a side view of my improved clamping mechanism attached to-an ice-skate. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a side view of my improved clamping mechanism forming part of a roller-skate,- and Fig. 4 is a plan view of Fig. 3.

Referring to Figs. 1 and 2, A is the runner of the skate and B is the heel-plate, secured to the runner in the present instance by riveting.

D is the sole-plate, secured also to the runner, and is merely a guide for the clamp-frame E, which is made in the form of a T, as shown, having a longitudinal arm 6 and transverse arms ff, provided with upright extensions f, beveled, as shown, by preference, to the line of the sole of the shoe. The heel-plate B also has projections Z) b at the rear to receive the heel of the shoe.

The frame E is guided in the sole-plate D, the portion d of the sole-plate being sunken below the balance of the plate, and the frame E slides between the sunken portion and the top of the sole-plate. The arm 6 of the frame has a slot e to allow for the passage of an extension of the runner, which is secured to the plate D. Pivoted at g to the end of the arm 6 of the frame E is a block F, having an extension h and a lip h. Through an orifice in the lip h passes a screw-rod H, and confined between the lip h and H is a nut G, adapted to the threads on the screw-rod.

Inserted in the heel-plate B is a disk I, to which is secured a lever J. One end of the screw-rod is pivoted to the disk and lever by a pin 2', which is to one side of the center of the disk I, forming a lever, so that on moving the lever J in the direction of its arrow, Fig.

2, the sole-clamp will be moved away from the heel-clamp, and by moving it in the opposite direction, as shown by the arrow, the sole-clamp will be moved toward the heelclamp, and if the shoe is in position the clamps will be firmly clamped to the sole.

The lever J and its disk are for the sole. purpose of clamping the skate to the sole of the slgoe, While the adjustment of the nut on the screw-rod is for the purpose of altering the size of the skate to fit different-sized shoes.

The object is to make a comparativelyoheap skate in two or three sizes, and the intermediate sizes are secured by the abovedescribed adjustment.

In Figs. 3 and L I have shown a rollerskate in which my invention is carried out.

In this case the sole-plate D is practically dispensed with, the foot resting on the clampframe E, which also carries the front rollers a a and their bearings a. The frame E in this instance is guided by a projection B, extending from the heel-plate B, lips c c of the frame extending down on each side of -the extension B, thereby preventing any twisting of the parts. It will be understood that the extension 13 can carry the. lips, instead of the frame E. The block F is pivoted to the frame E at g in the same manner as shown in Figs. 1 and 2; but the pivot-pin passes through a slot 0 in the extension B, so as to allow for the adjustment of the two parts.

The heel-plate carries the two rollers a a and their bearings a, and the rod H has the adj usting-nut'G, and is connected to the disk I, at z', in the same manner as that shown in Figs. 1 and 2.

I claim as my invention 1. The combination, in a skate, of the heelclamp and the sole-clamp, confined transversely, but free to move longitudinally, with mechanism for the longitudinal adjustment of one in respect to the other to aocommo- 5 date different sizes of shoes, and additional mechanism for adjusting the said clamps to clampv the sole to the skate, substantially as described.

2. The combination of the heel-plate, the loo disk thereon, and screw-rod pivoted to said disk and provided with a nut confined in a block, with the sole-clamping frame pivoted to said block and confined transversely, but free to move longitudinally, substantially as and for the purpose set forth.

The combination, in a skate, of the heelplate B and the sole-plate D, both carried by the skate-runner A, with a longitudinal clamp TO plate E, confined transversely to said soleplate D, but free to move longitudinally therein, and mechanism for moving said clamp-plate, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two sub- 15 scribing Witnesses.
